202 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 4
Suborder CALYPTOBLASTEA
Family Campanularidae
Genus GAMPANULARIA
Gampanularia altitheca, new species
Plate 23, Fig. 3
Trophosome.—Colony, 20 mm, consists of a fascicled, unbranched
stem, and hydrothecae with long pedicels. There are not many tubes in
the fascicle; each one, instead of ending abruptly, passes out to form the
pedicel of a hydrotheca, the terminal one being much longer than the
others, the free portion 3.5 mm in length; the pedicels of the others, although not so long, are still of considerable length, up to 2 mm. Each
pedicel has 2-3 annulations at the base of the hydrotheca; those that terminate the tubes of the fascicle have no other annulations; those that do
not have 1-3 annulations at the base. The hydrothecae are large, 1.0 x 0.5
mm, not far from being cylindrical except for the rounding of the base.
The margin is provided with 10 emarginate, deeply-cut teeth.
Gonosome.—Gonangia grow from the tubes of the fascicled stem,
much similar in shape and size to those of C. flexuosa Hincks (2.0 x 0.5
mm), nearly cylindrical, tapering to the base, and truncate distally, the
walls slightly wavy, or sometimes definitely corrugated.
Distribution.—Station 1012-39, south of Pyramid Cove, San Cle-
mente Island, Calif., 55-69 fathoms: gonosome, Station 618-37, San
Jaime Bank, off Cape San Lucas, 75 fathoms; 2y2 miles SE of Seal
Rocks, Santa Catalina Island, 87-90 fathoms; 4 miles north of Todos
Santos Island, Lower Calif., 40 fathoms.
Campanularia (?) castellata Fraser
Gampanularia castellata Fraser, Some new and previously unreported

Fraser, Hyd. Pacific Coast, 1937, p. 59.
Distribution.—3 miles east of South Point, Santa Rosa Island, 17-18
fathoms; off San Nicolas Island, 28-31 fathoms; east of San Esteban
Island, Gulf of California, 20-70 fathoms.
